AC Contactor Replacement in Boca Raton, FL
The contactor is a relay switch inside your outdoor unit that opens and closes to send power to the compressor and condenser fan. When it wears out or gets stuck, your system either won't turn on at all or won't shut off when it should. Burned or pitted contacts are the most common failure mode. A stuck-closed contactor is harder on your compressor than no cooling at all, because it runs the system outside normal operating cycles.

When to Call
When You Need AC Contactor Replacement
- The outdoor unit keeps running after the thermostat reaches setpoint and shuts off.

- Your outdoor unit surges on and off rapidly within seconds during a startup attempt.
How It Works
Our Process for AC Contactor Replacement
- 1
Contactor Inspection
We visually inspect the contact points for pitting, burning, or coil damage and test coil voltage to confirm the contactor is the fault.
- 2
Power Isolation
We disconnect power at the outdoor disconnect and verify no voltage is present before removing the contactor from the unit.
- 3
Replacement Installation
We install a matched replacement contactor, reconnect all wiring in the correct terminals, and confirm secure connections before restoring power.
- 4
Cycle Test
We restore power and command the thermostat through a full cycle, confirming the contactor pulls in cleanly and releases on shutdown.
Boca Raton Context
Why this matters in Boca Raton
Boca Raton's storm season brings power fluctuations that accelerate contact wear. Lightning-induced surges can pit contact surfaces in a single event. This is one of the more common service calls we see in the weeks following a major storm.
Straight Talk
About pricing & scope
Contactors vary by amperage rating based on your system size. Higher-tonnage systems require heavier contactors. If the existing contactor caused a hard start condition, we'll check the compressor and capacitor for secondary wear.
